4186 Single IRB and the CTSI: Liaison Model for the IRB Reliance Process
OBJECTIVES/GOALS: Navigating the NIH Single IRB Policy has been challenging for investigators, study teams, and Human Research Protection Programs (HRPP). In response, the Indiana Clinical and Translational Sciences Institute (CTSI) created an innovative

ABSTRACT Background Pediatric sarcomas are a heterogeneous group of tumors that contribute disproportionately to cancer mortality in children. Although congenital anomalies are among the strongest known risk factors for childhood cancer, the risk of specific sarcoma subtypes among affected individuals has not yet been thoroughly evaluated. Procedure We

A single WNT enhancer drives specification and regeneration of the Drosophila wing
The wing is a remarkable evolutionary novelty in insects. Here the authors demonstrate that the specification and regenerative capacity of the wing relies on a single wing-specific enhancer of the wingless gene in Drosophila.

Supporting Survivor‐Centered Care Through Digital Health Integration
ABSTRACT Survivors of childhood cancer face barriers to receiving guideline‐based, long‐term follow‐up care. Two digital tools, Passport for Care (PFC) and Cancer SurvivorLink (SurvivorLink), address complementary gaps by enabling tailored survivorship care plan (SCP) generation, updating, storage, and sharing.

Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.

A genome editing approach to study cancer stem cells in human tumors
The analysis of stem cell hierarchies in human cancers has been hampered by the impossibility of identifying or tracking tumor cell populations in an intact environment.

When IRBs Say No to Participating in Research about Single IRBs
ABSTRACTIn response to a policy of the National Institutes of Health and requirements in the revised Common Rule, a protocol for a multisite study must be reviewed by a single institutional review board (IRB), rather than by the IRB at each study site. The goal of the single IRB approach is to increase the efficiency of IRB review of multisite research

Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Mesenchymal cells contribute to tumor angiogenesis by regulating proliferation and migration of endothelial cells. Here, the authors show that mesenchymal stem cells also have the ability to acquire an endothelial phenotype upon TGF-β stimulation via the
